When male mice heterozygous for a small deletion on Chromosome 2 are mated to normal females, deletion-bearing offspring have thin bodies and are slow-moving, while non-deletion-bearing offspring are normal. However, when females heterozygous for the same deletion are mated to normal males, all offspring are normal. a. What mechanism likely explains this pattern of transmission? 1 pt b.

Why would offspring of females heterozygous for the deletion have normal offspring while those of males heterozygous for the deletion produce a mixture of affected and unaffected progeny? Supplement your explanation with a figure if possible. 2 pts
